The lightsaber sound was created for the original Star Wars film in 1977 by sound designer Ben Burtt, who combined a film projector motor with television interference to make the hum. Ignition and movement were shaped with additional electronic tones, giving each blade a living quality. Sith blades, shown as red in the films, became linked with the dark side and its users, including Darth Vader. The ignition effect remains widely reused in fan edits, games and parodies because audiences instantly identify the weapon and its threat.
